Abstract
Systems and methods for providing controlled friction in a haptic feedback device are described. One described device comprises a magnetic target, a magnetic core configured to be in communication with the magnetic target to provide a haptic effect, and a partition. The partition may be configured to maintain a magnetic circuit air gap between the magnetic target and the magnetic core, and to provide friction between the magnetic target and the magnetic core. Such a device may include a processor in communication with the magnetic core for providing a haptic effect.
